MACHINE FOR MAKING COP-TUBES.

SPECIFICATION forming partof Letters Patent No. 661,152, dated. November 6, 1900.

Application filed June 23, 190d. Serial No- 21,260. (No model.)

To ctZZ whom it may concern.-

Be it known that I, WILLIAM J. MOGAUS- LAND,of Camden,county of Oamdemand State of New Jersey, have invented an Improvement in Machines for Making Cop-Tubes, of which the following is a specification.

My invention has reference to machines for making coptubes; and it consists of certain improvements,which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a suitable construction of machine which shall automatically and rapidly produce perfect cop-tubes having special construction, more particularly set out in another pending application of mine bearing even date with this.

Generally speaking, the cop-tube for which my present machine is adapted is formed by winding a specially-shaped piece of paper.

upon a tapering mandrel, the said paper being out from a continuous paper-roll after paste orglue has been applied to the surfaces thereof in a predetermined manner, the object being to secure a cop-tube having a pliable body and a more or less hardened upper and smaller end which shall resist to a greater extent than usual the tendency to break down or become injured under pressure.

In carrying out my invention I provide means for intermittently feeding a strip of paper by suitable rolls and apply upon the opposite faces thereof paste or glue in such a manner that the paste on one side will secure the coils of the finished tube togetherin the body portion and the glue on the other side will act to strengthen the small end of the tube so formed. The paper strip so prepared with glue and paste is fed into a tapered mandrel and at the same time out off in given lengths by a suitable shears or cutter. The mandrel is then rotated to coil up the small specially-formed sheet thus prepared, and after it has been completely coiled the mandrel is withdrawn through a stripper and the tube dislodged and allowed to fall into the receiving-receptacle. If preferred, the tube may be formed of sized or calendered paper to impart additional strength to the body of the tube, and when such material is employed -I prefer to abrade or mechanically soften the edgeof the paperin passing through the feedingrollers,so that said edge which comes upon the outer surface of the tube shall positively adhere to the body of the tube and avoid the possibility of its uncoiling.

Fig.5 is a plan view showing the mandrel and paper sheet ready to be coiled. Fig. 6 is a crosssection of same on line 6 6. Fig. 7 is an inverted plan view of the paper sheet shown in Fig. 5. Fig. 8 is a perspective view of the finished cop-tube, and Fig. 9 is an elevation of the intermittently-acting spiral ears.

A. is the main frame of the machine, and O O and FF are two pairs of feeding-rolls, between which the paper web passes. The roll of paper B is hung in the lower part of the machine and the end thereof is passed up over a guide-roll b, thence between feed-roller O and pasting-roll D, which runs in a vat of. The paper after being thus pasted passes around the roller 0 and between itand the feed-roll O. The roller O is' recessed in its surface, so as not to squeeze out the paste. The upper surface of the web of paper is thus pasted for the greater part of its Width, as in dicat-ed at D in Fig. 5. The width of the layer of paste corresponds to the length of the pasting-roller D. As the web of paper passes from the rollers G C to feed F F a pastingroller E, having curved paste-applying surfaces 9, applies paste or glue to the under sur-- face of the web at given distances in its length. These correspond to the glued part-s E. (Shown in Fig. 7 and indicated in dotted lines shown in Fig. 5.) The web thus pasted is fed over a table'l and is cut off on a curved line, as indicated in Fig. 5, by the curved shears S. In this manner the sheets to be coiled into the cop-tube are formed with parallel straight edges in one direction and parallel curved edges in the other direction One of the straight edges of the paper sheet-namely, that edge adjacent to the unpasted portion of the upper surface-is received in a groove on of the mandrel, which is made tapering, as shown in Fig. 5. At the time that the paper strip is cut off to subdivide it into sheets the said sheet is held in position by a clamp R, which temporarily holds the sheet on the table. The mandrel. then begins to rotate, and the pressure of the clamp R is removed, permitting the sheet to be coiled upon itself about the mandrel until it assumes the construction shown in Fig. 8. A spring-plate t presses the paper against the mandrel as it rotates and is moved away from the mandrel by a cam 25 when it is discharging the tube.

The mandrel M is formed on the end of a reciprocating and rotating shaft M, which is rotated by a pinion N, concentric with it, said pinion being driven by a spur-gear N on a rotating shaft Q. The shaft Q is iutermittently rotated by means of spiral gears, one of said gears, Q being upon the shaft Q, and the other, Q, upon the power-shaft K, which is driven by suitable belt-pulleys L. Gear Q is of twice the diameter of gear Q and has one half of its circumference provided with teeth and the other half with a longitudinal rib g, which looks the gear 1 in a stationary position, so that the mandrel is caused to rotate intermittently, being held stationary for about the same period that it is rotated. \V hen stationary, the mandrel is reciprocated to dislodge the cop-tube. The mandrel-shaft M is drawn back or in one direction by means of a band 0, connected to a collar 0 on its end, guided over a guideuoller O, and hav ing its other end connected to a spring The mandrel-shaft is moved in the opposite direction or into position for coiling by means of a pivoted arm P, acting upon the end of the mandrel-shaft or a ball-bearing therein and moved under the action of a cam 19 on the power-shaft K. In this manner the mandrel is alternately rotated and reciprocated. When the mandrel is withdrawn by the action of the spring after the tube has been coiled upon it, it passes through the stripper W, which strips otf the finished tube and permits it to fall down into a suitable receptacle. All of the rollers C, C, F, I E, and D are geared together by a suitable train of gears G, so that they all run at the same surface speeds. Power is supplied to this train of gears by means of a pinion 7L, driven by means of spiral gears H, similar to the gears Q Q -one of said gears being rigid with the pinion 7L and the other being secured to a shaft 1, extending the length of the machine and receiving power from the shaft K through bevelgears J. The pinion h is preferably geared with the spur-wheel on the'pasting-roll D; but this is not essential, as it may mesh with any of the gears of the train, provided the right direction of rotation is secured. By this means the train of gears Grand the feeding-rolls and pasting-rolls are moved intermittently, and vice versa, with the rotations of the mandrel.

The shaft I is provided with a cam s for operating the shears S and a cam r for operating the clamp R, as indicated at Fig. 4. It also has the cam '6 for operating the springplate 1, before referred to. The proportions and constructions of the various gears are such that the feeding action on the paper strip shall insure the requisite length of paperbeing fed over the table Tsuflicient to form the length of the tube, and this extent of paper must be fed between each series of revolutions of the mandrel or while the mandrel is making its reciprocations, so that upon the mandrel taking its position indicated in Fig. 1 it will have received the edge of a fresh sheet and be ready to wind it into a tube.

lVhere the paper is sized and calender-ed it is important to abrade or soften the edge thereof farthest from the mandrel, and this is accomplished by providing the rollers C C with milled surfaces 0 adjacent to one end, one of said milled surfaces operating on the upper part of the sheet and the other upon the lower part. It is also preferable that the milled edges shall be differently formed, so as to break down the texture of the paper adjacent to this edge, whereby it will more readily retain its position after being pasted down. It is evident, however, that while it is convenient to provide these milled surfaces on the rollers G 0 they may he formed on any other roller or rollers, and, if desired, one of them alone may be used.

\Vhile I prefer the general construction herein set out as being excellently adapted for the purposes of my invention, I do'not limit myself to the minor details, as they may be modified in various ways without departing from the Spirit of the invention.
